That rhythmic "slurp, slurp, slurp" from the other room—sound familiar? A quick lick after a muddy walk is perfectly normal. But when your dog can't leave their paws alone, it often signals something more than just a bit of cleaning.
Dogs bite their paws and nails for reasons ranging from allergies and infections to boredom and hidden pain. The key is spotting the difference between a quick clean-up and a compulsive habit that needs attention. This guide breaks down the common causes UK dog owners face throughout the year and helps you know when to step in.

This article provides general information for UK dog owners. It is not veterinary advice and should not replace professional consultation. If your dog shows persistent paw biting, limping, swelling, bleeding, or discharge, please contact your vet immediately. The PDSA, Kennel Club, and other sources referenced here offer guidance, but every dog's situation is different.
Think of it like this: a dog uses their mouth much like we use our hands. A quick lick after a walk is no different from you brushing mud off your jeans. The problem starts when that cleaning becomes constant.
Healthy grooming is sporadic and relaxed. Most dogs finish a quick clean-up in 10 to 15 seconds, usually after coming in from outside. They're calm, not frantic. Once done, they move on. If your dog settles after a brief lick and goes about their day, there's nothing to worry about.
The PDSA notes that paw licking can become a coping mechanism—dogs sometimes continue the habit even after the original itch is gone because it made them feel better.[1] Here's what to watch for:
If you're seeing any of these signs, it's time to look at what might be driving the behaviour.
Our climate and terrain introduce specific triggers at different times of year. Knowing what to expect each season helps you stay one step ahead.
Rising pollen counts from grasses and trees trigger allergic reactions in many dogs. Research suggests that approximately 10–15% of dogs suffer from atopic dermatitis, with paw licking often being one of the first visible symptoms.[2] Your dog doesn't need to touch pollen directly—allergens in the air can settle on their coat and cause reactions even on their feet.
Grass seeds pose a serious risk. Foxtail-type seeds have barbed ends that can pierce the skin and migrate deeper into tissues, potentially causing abscesses and infections.[3] Check between your dog's toes after every walk through long grass. If a seed burrows in, it won't come out on its own—you'll need a vet to remove it.
Hot pavements are another summer hazard. The Kennel Club recommends the "seven-second rule"—place the back of your hand on the pavement and if you can't hold it there for seven seconds, it's too hot for your dog's paws.[4] On a 31°C day, tarmac can reach 62°C or higher—enough to cause burns and blistering.
Harvest mites are a common cause of itchy paws in UK dogs during late summer and autumn. Their larvae appear as tiny orange or red dots, typically clustering between the toes, in the armpits, or around the ears. The PDSA notes these mites are really irritating for dogs, prompting intense licking and scratching.[5]
Road salt and de-icers can dry out and crack your dog's paw pads, causing discomfort that leads to licking. Some de-icers also contain chemicals that irritate the skin or can be harmful if ingested when your dog licks their paws.[6] A quick rinse in cool water after winter walks makes a real difference. For more detailed advice, see our guide to winter paw care in the UK.
When paw biting becomes persistent, there's usually an underlying physical reason. Here are the most common culprits UK vets see.
Allergies are the leading cause of paw licking in dogs. The PDSA confirms that skin allergies can cause a reaction even if your dog's paws haven't actually touched whatever they're allergic to.[1]
Triggers include:
Rinsing your dog's paws in cool, plain water after each walk can help remove allergens before they cause a flare-up.
Yeast infections (Malassezia) are one of the most common causes of paw problems. PetMD notes that dogs with yeast infections often have a musty odour, greasy coat, and tend to lick the affected areas excessively, leading to brown discolouration of the skin over time.[7]
Signs of a yeast infection in your dog's paws:
Bacterial infections typically present with swelling, pus, and sometimes a foul smell. Both types need veterinary treatment—don't try to manage them with home remedies alone. For more information on managing yeast infections, see our guide to the best dog shampoo for yeast infections in the UK.
Fleas and ticks love to hide in the webbing between toes where they're hard to spot. According to the PDSA, while fleas don't often live on the feet directly, if your dog can't scratch the fleas elsewhere, they might start licking their paws instead as a distraction.[1]
Regular flea and tick prevention is essential. If you're seeing persistent paw problems despite treatment, ask your vet about checking for other mites like Sarcoptes (mange) or Demodex.
Overgrown nails can curl into the paw pad, causing pain. Brittle or cracked nails can also split, catching on surfaces and causing sharp discomfort. Either issue can prompt your dog to bite at their nails compulsively.
Regular nail trims—either at home or with a Professional Dog Groomer—keep nails at a comfortable length and prevent many problems before they start. For a complete guide on trimming your dog's nails safely at home, see our article on how to trim dog nails: clippers vs grinder.
The Casfuy Dog Nail Grinder offers a gentle, professional-grade alternative to clippers. With 2-speed settings and quiet operation, it's ideal for nervous dogs or those with dark nails where the quick is hard to see.
Something as simple as a thorn, splinter, or small stone lodged in the paw can cause constant irritation. Purely Pets Insurance notes that blades of grass, small stones, or other debris can easily get lodged in your dog's paw, causing discomfort and prompting them to bite their nails.[8] If your dog suddenly starts biting at one specific paw, check carefully between the toes and around the pad.
Not every case of paw biting has an obvious physical trigger. Sometimes the cause lies deeper—either hidden pain or behavioural factors that are easy to miss.
The PDSA points out that dogs sometimes lick their feet or joints because they're stiff and sore, just as we might rub a sore patch.[1] If your older dog has started chewing their paws with no visible skin problem, consider whether joint pain from arthritis could be the underlying issue.
High-energy breeds are particularly prone to paw chewing when under-stimulated. Collies, Spaniels, and Terriers—common across the UK—need mental and physical outlets. When they don't get enough, chewing becomes a way to pass time.
The PDSA notes that boredom and stress can cause dogs to lick and bite their front paws out of frustration, which can then become a habit.[1] If your dog seems to chew more when they've had a quiet day, this could be the cause.
Chewing releases feel-good chemicals in a dog's brain. Preventive Vet notes that sniffing, licking, and chewing release serotonin, dopamine, and endorphins—what they call the "calming trifecta."[9]
Dogs dealing with separation anxiety, household changes, or general stress may chew their paws as a way to cope. This can become a compulsive habit that continues even when the original stressor is resolved. If you suspect anxiety is the root cause, the PDSA recommends seeking advice from your vet or a behaviourist accredited by the Association of Pet Behaviour Counsellors (APBC) or the Animal Behaviour and Training Council (ABTC).[1] For more on helping anxious dogs, see our comprehensive guide on how to calm an anxious dog.
Professional groomers are often the first to spot early warning signs of paw problems. They see your dog's feet close-up and have trained eyes for subtle changes you might miss at home.
A qualified groomer (look for City & Guilds Level 3 or equivalent) will typically check:
Groomers can provide targeted care that's difficult to do at home:
Regular grooming appointments—whether at a salon or with a mobile groomer—create a routine health check for your dog's paws.
Prevention beats treatment. Here's what you can do at home to keep your dog's paws in good condition.
After every walk, rinse your dog's paws in cool water. This removes allergens, salt, and any debris before it causes problems. The PDSA recommends rinsing paws in cool, plain water after walks if your dog has allergies.[1]
The crucial step many owners skip: thoroughly dry between the toes. Moisture trapped in these spaces creates the perfect environment for yeast to grow. A quick wipe with a clean towel makes a real difference.
The Dexas MudBuster Portable Dog Paw Cleaner makes post-walk paw cleaning quick and easy. Its soft silicone bristles gently remove mud, dirt, and allergens without the mess—just add water, insert the paw, and twist. Available in multiple sizes for all breeds.
Use dog-specific paw balms containing ingredients like beeswax or shea butter to hydrate dry pads. Avoid human hand creams—they can be toxic if licked and may soften pads too much, making them more vulnerable to damage.
In winter, you might consider dog boots for walks on heavily salted roads, though many dogs need time to adjust to wearing them.
The Musher's Secret Paw Protector (200g) is a 100% natural, food-grade wax that forms a breathable barrier against salt, ice, hot pavements, and allergens. Used by sled dog mushers, it's lick-safe, scent-free, and contains vitamin E to moisturise dry, cracked pads.
If boredom is driving the paw chewing, give your dog something better to do. The PDSA suggests puzzle feeders, interactive toys, and destruction boxes as ways to keep dogs mentally occupied.[1] Extra walks or garden playtime can also help.
Long-lasting chews provide an outlet for the chewing urge while keeping paws out of the equation.
Keep your dog's mind busy with these popular options:
Don't wait until a small problem becomes a big one. Early treatment is usually simpler, cheaper, and less stressful for your dog. The PDSA emphasises that getting help early will make paw problems much easier to fix.[1]
Your vet can diagnose the underlying cause and provide appropriate treatment—whether that's allergy management, infection control, pain relief, or referral to a behaviourist for compulsive cases.
A dog biting their paws and nails isn't just a quirky habit—it's their way of telling you something needs attention. Whether it's allergies, hidden pain, seasonal hazards, or simple boredom, the cause matters.
The good news: most paw problems respond well to treatment once you know what you're dealing with. Regular grooming, simple home care, and knowing when to involve your vet create a solid foundation for keeping your dog comfortable and their paws healthy year-round.
